Quantitative micro‐XRF combined with X‐ray imaging reveals correlations between Zn concentration and dentin tubule porosity across entire teeth

open access: yesVIEW, EarlyView.
The combination of calibrated micro‐CT and quantitative micro‐XRF measurement facilitates the correlation of density and composition in the 3D macro‐structure of teeth. Zn concentration in dentin increases by a factor of 10 toward the pulp. Incidentally, the overall density decreases, showing an association between Zn and the dentin tissue porosity ...

TRANSLIENT: Detecting Transients Resulting from Point-source Motion or Astrometric Errors

open access: yesThe Astronomical Journal
Detection of moving sources over a complicated background is important for several reasons. First is measuring the astrophysical motion of the source. Second is that such motion resulting from atmospheric scintillation, color refraction, or astrophysical

SMART CITY CONTROL ROOMS: The Rewiring of Local Governance Landscapes in India

open access: yesInternational Journal of Urban and Regional Research, EarlyView.
Abstract Smart city control rooms are prominent components of the smart city discourse. They embody a long‐standing dream to visualize and manage multiple urban processes in real time through the collation of data flows. Previous research has produced important insights into the design, construction and operation of these facilities.

The Submillimeter Wave Astronomy Satellite Attitude Control Software Design

open access: yes, 1995
The Submilimeter Wave Astronomy Satellite (SWAS) was selected for flight by NASA in 1989 as a part of the Small Explorer (SMEX) program. SWAS's primary science objective is to conduct high spectral resolution surveys of galactic molecular clouds. The SWAS Attitude Control System (ACS) is three-axis controlled, zero momentum stabilized, and is capable ...

Estimating the Carbon Footprint of External Beam Radiotherapy: Should This Be a Concern for LMICs?

open access: yesJournal of Medical Imaging and Radiation Oncology, EarlyView.
ABSTRACT Purpose This study aims to estimate the carbon footprint associated with external beam radiotherapy in a low‐ and middle‐income country (LMIC) context, specifically at the Uganda Cancer Institute (UCI), and to evaluate whether sustainability should be a priority alongside treatment access in such radiation therapy settings.

Cerebrovascular Function in Women With Polycystic Ovary Syndrome: A Pilot Multi‐Parameter Magnetic Resonance Imaging Study

open access: yesClinical Endocrinology, EarlyView.
ABSTRACT Objective Polycystic ovary syndrome (PCOS) is associated with an increased risk of cerebrovascular disease, but the effects on cerebrovascular function are unknown. In this pilot study, we sought to compare cerebrovascular perfusion, pulsatility, reactivity and metabolism between women with PCOS and healthy volunteers using MRI, and ...

Supernova Burst and Diffuse Supernova Neutrino Background Simulator for Water Cherenkov Detectors

open access: yesThe Astrophysical Journal
If a Galactic core-collapse supernova explosion occurs in the future, it will be critical to rapidly alert the community to the direction of the supernova by utilizing neutrino signals in order to enable the initiation of follow-up optical observations ...
